Yup.. that's what we're doing. I've checked the database and all properties I can see on the server, and everything looks peachy, but the site creeps along once in a while. I've sent a support ticket in. Let's see how responsive they are!

Finally got the problem escalated to tier 3 support. Turns out the problem was on their end.

Essentially, a conflict with the kernel hook used by our backup system was causing IO spikes and driving up the load. The kernel on the server has been rebuilt and everything appears to have returned to normal. We apologize for the inconvenience.

Space has also been increased to "Unlimited"... so I've upped the image size again to 1600x1200 and 4 meg. Lets see how "unlimited" it really is...
